OO Bench compares the speed of the same object-oriented tasks in several object-oriented languages. C++, Objective-C, and Java are currently supported. Support for Smalltalk, CLOS, CSharp, and Eiffel are in development. It aims to be simple, easy to understand, and easy to port. It also aims to follow the idioms and best practices advised by each language as much as possible. It is designed to make it easy to look up how a particular problem is best solved in another language.
